commit 1a6be82a56458a55a6e6a489c0672b1bec444704
Author: Bob Peterson <bob@ganesha.peterson>
Date: Tue Jan 19 13:51:13 2010 -0600
Attach bh's to inodes
This patch attaches buffer_heads to inodes. This gives us better
performance because we don't have to constantly keep searching for
the buffer based on the dinode address. It's also another step in
eliminating the linked list of buffers altogether.
